Write an equation in slope intercept form for the line that has a y intercept of 3 and a slope of -2
charle [14.2K]

Answer:

-2x + 3

Step-by-step explanation:

Trust me, this is the answer.

An explanation:

Slope is rate of change.

if the lady sells 2 cakes in 3 hours, her rate of change, or slope is 2/3.

Y-intercept is where the data enters the graph. It will not always be at the origin of the graph. If on the lady's first day of business, she sold 10 cakes, the  Y-intercept is 10. This equation of the lady's business in slope intercept form would be 2/3x + 10. ALWAYS write the slope before x and the y intercept after the + or -- , hope this helps, but -2x + 3 is your answer for sure.

George is cooking an elaborate meal. He can only cook one thing at a time in his microwave oven. His turkey takes 90 ​minutes; t
AysviL [449]
<h2>Answer :</h2>
  • He need 111.75 minutes to cook the meal
  • He need to start at 2.08.15 P.M. in order to complete the cooking at 4 P.M.

<h2>Step-by-step explanation :</h2><h3>Known :</h3>
  • George can only cook one thing at a time
  • Turkey takes 90 minutes to cook
  • Pumpkin pie takes 20 minutes to cook
  • Rolls take 60 seconds to cook
  • A cup of coffee takes 45 seconds to heat

<h3>Asked :</h3>
  • Time needed to cook the meal
  • Time he need to start in order to complete the cooking at 4 P.M.

<h3>Completion :</h3>

Let's convert all the seconds to minutes. We know that 60 seconds is equal to one minute. So,

60 seconds = 1 minutes

45 seconds = 45/60 minutes = 0.75 minutes

Time needed = Turkey + Pumpkin pie + Rolls + Coffee

Time needed = 90 + 20 + 1 + 0.75

Time needed = 111.75 minutes

Then, we'll calculate the time he need to start in order to complete the cooking at 4 P.M. First, let's convert the minutes to clock format.

111.75 minutes = 1 hour and 51.75 minutes

111.75 minutes = 1 hour and 51 minutes and 45 seconds

Lastly, calculate the time he need to start in order to complete the cooking at 4 P.M.

4h 0m 0s - 1h 51m 45s = 2h 8m 15s

<h3>Conclusion :</h3>
  • He need 111.75 minutes to cook the meal
  • He need to start at 2.08.15 P.M. in order to complete the cooking at 4 P.M.

Given m ZLMN = 145°, what is m ZXMN?<br> Show all relevant work.
myrzilka [38]
80 degrees. 145 = (4x+5) + (6x-10) = 10x-5... so 10x = 150, x = 15. LMN = 6x-10 = 6(15) - 10 = 80.
